Abstract

In this paper the Author studies the propagation of discontinuity waves of order r (r=O or through an anisotropic mixture of two linear homogeneous elastic solids, each having the same constant temperature. By using the method of Nariboli, it is proved that under suitable hypotheses there exist six possible real formal speeds of propagation of the wave front. Moreover the growth equations of the discontinuities along the rays are established and integrated. The speeds of propagation and the evolution law are the same as those of the waves of order 1 ([1]).
